Visual C++ :: How To Insert A String Right In The Middle Of Another String
Nov 16, 2014
I'm new to strings. I want to know how to insert a string right in the middle of another string.Is it possible to do that? for example my first random word is 12345678 and the 2nd random word is jimmy I would have to write .
This in my code uno.insert(4,dos); for jimmy to be printed in the middle of the first string,but what if my 1st random word is has more than 8 characters what would I do in that case?
I'm trying to make a function that lets me pass an index and a string and will insert the string at that index in the linkedlist... here is so function i have so far:
What is the efficiency of the two assignments (line 1 and 2), i.e. (function calls, number of copies made, etc), also the Big O notation. I know there are function calls for retrieving the size of each string in order to produce a new buffer for the concatenated string...any difference between line 1 and 2 in terms of efficiency?
String s("Hello"); String t("There"); 1. s = s + t; 2. s += t;
I made a simple little program that takes text from the clipboard, and spits out all the lines I've copied one at a time (so my program can analyze it).
everything works perfectly, except, it spits it own in the wrong order, I want it to spit out from bottom to top. but currently it spits out the data from top to bottom. here is my code :
Code: #include <iostream> #include <Windows.h> #include <string> #include <sstream> using namespace std; int main() { HANDLE clip; // assigns the var. clip to hold a handle ID.
[Code] .....
I want this loop to run backwards! Like it say's what I want to work backwards. Where as I know how to flip a while loop like this: while(x < 5), how to flip a loop like the one I'm using. how I can do this?
I am using Visual Studio 2008. I just wonder if there are any library function in Windows SDK or MFC, or from third-parties, that can convert a UTF-8 string into Windows Unicode string(used in CString object).
Can MultiByteToWideChar or ATL String conversion macro like A2W to the conversion?
Ok, so I'm writing this code and when I build it keeps saying cannot implicitely convert type int to string even though I declared my variables as string. Why is it giving me this error?
private static string Repair() { string result=""; string beep; string spin; Console.WriteLine("Does your computer beep on startup?:(y,n)");
I would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.
Code: #include <stdio.h> #include <string.h> int main() { char str[100]; int i = 0;
[Code] ....
Now I understand that it returns the count in "int" so my question is:
Let's say i declared
Code: int count = 0; at the beginning of the code and then made Code: count = strlen(str); why wouldn't i have the same result? Is there a way to do it also?
I have this string d ="3 J JD, K" and i want to split the string to individual string. I have this code which eliminates the comma but doesn't split the string into individual string.
#include <iostream> #include <string> #include <sstream> using namespace std; int main() { string str = "3 J JD,K"; stringstream ss(str);
[Code] ....
Output of the code is 3 J JD k
but I want 3 J JD K
Also after I split the string is there any way to put the split string into individual string variables.
Very new to programming, and I know that there must be another way on inputting a string into each array cells not by just inputting it one by one, but as a whole. My code at the meantime is: [URL]
I have problem with string compare. I want to compare the string user input with a string in binary. And I don't know how to do it. Problem in function login();Here is the code: And you also can download file in attachment too..
In this code, i declared a string constant and trying to print the length of string. I know that if i write char a1[7] or char a1[] than it runs and give aggregate output, but in this case it is giving double length of string.
I wrote a program that reads a list from a file and stores it in a string type vector. Now, I want the user to input a word so that the program can search the vector to see if that word already exists. I have used every possible way of reading input from the console and storing it in order to compare with the vector but it never results in a match. When I print the input string and the vector string they are exactly the same thing (or at least print to the console as if they were). I've tried using getline; using cin direct to a string var; using cin to a char array and then casting to string using string str(arr); I even added a newline at the end just in case and STILL I cannot get a match.
vector <string> currentSet; //read a list in from a file and has 9 items in it cin.ignore(); string line; getline(cin, line); if(line == vector[0]){//if printed to console line is HEAT and vector[0] is HEAT cout<<"match"<<endl; }
write a program that prompts the user to input a string and outputs the string in uppercase letters. (Use a character array to store the string.) Does this follow the criteria? This program is very similar to one I found on these forums but I have one problem, it outputs everything backwards! EX: dogs will output to SGOD. What I need to do to make it output correctly, I think it may have to do with getline?
#include <iostream> #include <cctype> #include <cstring> using namespace std; int main() { char let[100]; cout << "Enter what you would like to be UPPERCASE: ";
The program then asks the user for a search string, which may contain white space. The program should search the file for every occurrence of the search string. When the string is found, the line that contains it should be displayed in the following format
nnnnn:Line Contents
That is the line number of the line, 5 columns wide, right justified, followed by a colon, followed by the contents of the line.
And this is what I've got so far:
Code: #include<iostream> #include<fstream> #include<string> #include<iomanip> using namespace std; int main(int argc, char *argv[]) { ifstream inFile; string fileName,
[code]....
But this doesn't work. It prints everything in the file, not just the lines where the string is found.
I have an assignment that is due on monday I am stuck on this function. I have to convert my netpay which is a float to a string So if i have 356.26 it should output the sum of three hundred fifty-six and 26/100 dollars my program function works for the sum of three hundred but after that it spits out garbage.
I have a problem in using ATL 7.0 string conversion macros.
My codes looks like this, which uses ATL 3.0 string conversion macros in the past:
Void Myfunc() { USES_CONVERSION;
LPSTR lpszA; LPWSTR lpszW; If (...) { CString strText; If (...) { If (bUnicode)
[Code]...
But since 3.0 macros do not support large strings, I want to switch to 7.0 macros, but have problems. Based on the [URL]... samples, I should declare CT2A pszA(strText) or CT2W pszW(strText) within the if and else bodies, as below:
However, in such a case, after running to the codes using lpszA or lpszW, both CT2A and CT2W will be destructed so lpszA and lpszW will be invalid. How to solve this problem?
